It does not set require
13、ments, i.e.dimensions and materials, for the manufacture of plugs. This International Standard applies to the drain, fill and level plugs required on earth-moving machines for the changing of lubricants, coolants, hydraulic oils and fuels. 2 Normative references The following standards contain provi
14、sions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the po
